Preventive dentistry / Plaque control

2. What is dental plaque :
Dental plaque is a soft sticky and
colorless deposit that accumulates
on the teeth

3. Plaque control
is the most essential Step towards
maintaining a proper and a healthy
Oral Environment .
Also it is the removal of microbial
plaque and the prevention of its
accumulation on the teeth and
adjacent gingival tissues

4.  Mechanical
 Chemical

5. 1-tooth brush
2-interdental aids
3-other
Individual mechanical plaque
control is achieved by :

6.  Mechanical
 Electrical

7. Design

8. • Soft brush: 0.007 inch(0.2 mm)
• Medium brush: 0.012 inch(0.3 mm)
• Hard brush: 0.014 inch(0.4 mm)

9. • Brush length: 1-1.25 inches
• Brush width: 5/16-3/8 inches
• 2-4 rows
• 5-12 tufts per row

10. • Gingival erosion
• Gingival recession
• Cervical abrasion
• Toothbrush
stiffness
• Method of
brushing
• Brushing frequency

12.  Bass method technique
 Modifid bass method
 Stillman method
 The charter method

13. Modified Stillman method. This method requires
placement of the sides of the bristles against the
teeth and gingiva while moving the brush with
short, back-and-forth strokes in a coronal
direction.

14. Bass method. A, Proper position of the brush in
the mouth aims the bristle tips toward the
gingival margin. B, Diagrams shows the ideal
placement, which could permit slight subgingival
penetration of the bristle tips

15. Charters method. The Charters method requires that
the bristles be pressed against the sides of the teeth
and gingiva.The brush is moved with short circular or
back-and-forth strokes

16. This brush position on occlusal surfaces of the
teeth is used with any technique, including the
Bass, Stillman, or Charters method.

18. They where introduced in 1939

19. Factors determining the
selection of interdental aids are
the type of embrasures :
 Type 1 :
 Type 2 :
 Type 3 :

20. It's the most commonly
recommend method of removing
plaque from interdental areas

23.  Gingival massage :
can be performed with a toothbrush
rubber tip stimulator or interdental
cleaning devices .
it produces :-
1-epithelial thickening
2-increased keratinization
3-increased mitotic activity in
epithelium and connective tissue

24. • Dental irrigation devices
• Tongue scrapers
• Dentifrices

25. They are several types :
1-use water faucet to irrigate between and
around the teeth the water is steady and is
controlled turning the fenced handle
2- use and intermittent water jet

27. These are the aid for cleaning and
polishing of teeth surfaces.
They are used in the form of powder
past ointment and gel

28. Composition :
1-fluoride
2-abrasions
3-detergents
4-humectants
5-thickeners
6-preservative
7-flavoring agents
8-sweeteners
9-coloring agents
10-anticaries agents
11-water

29. • Antiadhesive
• Antimicrobial
• Plaque removal
• Antipathogenic

30. • Toothpaste
• Mouthrinses
• Spray
• Irrigators
• Chewing gum

31. • ADA has accepted two agents for
treatment of gingivitis:
 solutions of chlorhexidine digluconate
mouthrinse
• essential oil mouthrinse thymol,
eucalyptol,menthol, and mythyl
salicylate work by altering bacterial cell
wall

32. • Chlorohexidine action:
• Increase bacterial membrane permeability
followed by coagulation of cytoplasmic
macromolecules
• Has substantivity ability of substance to
adher to the structur to be released for
long time
• Chlorhexidine-side effects:
• Brown discoloration
• Taste perturbation
• Oral mucosal erosion

33. • Solutions or wafer capable of staining
bacterial deposits on the surfaces of teeth,
tongue, and gingiva
• Erythrosine, fuchsin
• Fluorescein-containing dye

34.  Dental plaque is colorless deposit that accumulates on
the teeth
 Plaque control is the most essential Step towards
maintaining a proper and a healthy Oral Environment
 Plaque Control is done Mechanically and Chemically
 There are many technique for Brushing
 From the factors that determining the selection of
interdental aids are the type of embrasures
 Dental Floss It's the most commonly recommend
method of removing plaque from interdental areas
 Gingival massage produced epithelial thickening ,
increased keratinization , increased mitotic activity in
epithelium and connective tissue
